<br />forced concrete of substantial design and good quality. <br />They are first class in every respect. The dam is 420 <br />feet long, and is one of the simplest and least expen- <br />sive diversion weirs on the river, and at the same time <br />efficient and serviceable. It has successfully withstood <br />the ordeal of severe floods and ice jams, and is appar- <br />ently in perfect condition at the present time. <br /> <br />PROPOSEDENLARGEMEN~ <br /> <br />Experience in the use of this canal during the summer <br />floods of 1908 and 1909 was very satisfactory, as the <br />canal and its siphons operated successfully, and it de- <br />livered a very considerable quan:ity of flood water to <br />the Horse Creek Reservoir, and more recently, in 1910, <br />to the Adobe Creek Reservoir as well, helping to fiU up <br />the unavailab!e part of the latter reservoir in conjunc- <br />tion with water diverted from Adobe Creek. It was ob- <br />served, however, that there are so many high floods of <br />short duration in the river that a much larger canal is <br />needed to secure a fair proportion of what is going to <br />waste. Of course, if it were possible to conceive cf a <br />reservoir of large enough capacity built across the val- <br />ley abcve the head of this canal to impound all of the <br />water of maximum floods until it could be drawn off by <br />the canals leading to the subsidiary storage reservoirs, <br />it would be unnecessary to enlarge these canals to sup- <br />ply the reservoirs of this Company and those of the Great <br />Plain Storage Company. In the absence of such an ideal <br />equalizer the enlargement of the Storage Cana! is pro- <br />posed. FrorP the headgate to the siphon under the <br />Hclbrook Canal (12.3 miles), It is proposed to 'Ni:::len the <br />canal to a bottom width of 60 feet, and Increase :he <br /> <br />40 <br />
